As more communities focus attention on environmental sustainability, community forest management has become increasingly dependent on Geographic Information System (GIS) for Urban Tree Canopy (UTC) Mapping and Analysis. Understanding the importance of existing urban tree canopy is a key measure for identifying various types of community forestry management opportunities.
With advanced GIS and remote sensing software capabilities, Davey Resource Group's (DRG) GIS technicians utilize an object-oriented classification approach to process and analyze high resolution, remotely-sensed data which identifies tree canopy cover and land cover classifications.
The use of imagery analysis is cost-effective and provides a highly accurate approach to assessing your community's existing tree canopy coverage, which supports responsible tree management, facilitates community forestry goal setting and improves your urban resource planning.
A typical analysis involves:
- Existing secondary GIS data layers
- High resolution, remotely sensed data (satellite or aerial imagery)
- ESRI ArcGIS® vector-based polygon shapefile of the final tree canopy layers
- Final report of tree canopy cover and/or land cover classification statistics
Examples of Land Cover classes include:
DRG provides urban tree canopy analysis and land cover mapping services to a wide variety of clients.
